Description

Technical Field

[0001] This utility model relates to the field of metal plate processing technology, specifically to a drilling device for metal plates. Background Technology

[0002] In modern industrial production, metal sheets are widely used as basic structural components in many fields such as aerospace, automobile manufacturing, and machining. Drilling is one of the key processes in metal sheet processing, and its processing efficiency and quality directly affect the production cycle and performance of the product.

[0003] Currently, most drilling machines on the market use a single-axis drilling mode. This traditional drilling method has obvious limitations when dealing with metal plates that need to be drilled with multiple holes. When multiple holes need to be drilled, a single-axis drilling machine needs to process each hole sequentially, resulting in a slow drilling speed that is difficult to meet the needs of large-volume, high-efficiency production. In addition, after completing the processing of one hole, the plate needs to be manually removed, moved to a suitable position, and then fixed again. This process not only increases the labor intensity of the operators but also introduces the risk of processing errors caused by inaccurate manual positioning, greatly reducing drilling efficiency and increasing production costs. Utility Model Content

[0004] To achieve the above objectives, the present invention provides the following technical solution: a drilling device for metal plates, comprising an operating table, a clamping assembly installed at the center of the operating table, and movable adjustment assemblies distributed on both sides of the clamping assembly, wherein a multi-axis drilling device is installed at the movable end of the movable adjustment assembly opposite to the clamping assembly.

[0005] The clamping assembly includes a fixed plate and a mounting frame. A clamping plate is fixed on the fixed plate, and two sets of guide rods are passed through the clamping plate. A push plate is fixed between the guide rods. A push cylinder connected to the push plate is installed on the mounting frame. Multiple protrusions are formed on the top of both the clamping plate and the push plate.

[0006] The movable adjustment assembly includes a platform, on which a push cylinder is mounted, and a push plate slidably connected to and fixed to the piston rod of the push cylinder, wherein the multi-axis drilling device is mounted on the push plate.

[0007] The multi-axis drilling device includes a support plate, a housing fixed on the support plate, multiple drill bits rotatably connected to the housing, and a drive assembly for rotating the drill bits installed between the support plate and the housing.

[0008] Furthermore, rubber blocks are fixed to the opposite sides of the protruding ends of the clamping plate and the push plate.

[0009] Furthermore, an inner platform is formed on the side opposite to the protruding ends of the clamping plate and the push plate, and below the rubber block.

[0010] Furthermore, a limiting block is fixed on the clamping plate, the limiting block is opposite to the inner platform of the clamping plate, and a stop edge is formed on its side that is opposite to the gap between the clamping plate and the push plate.

[0011] Furthermore, the platform has multiple waist holes, and the platform is fixed to the operating table by screws passing through the waist holes. Two sets of fixing blocks are also fixed on the operating table, and screws are inserted between the fixing blocks and the platform. The screws are limited by multiple nuts on the outside.

[0012] Furthermore, the drive assembly includes a belt drive mounted on a support plate and a rotating shaft rotatably mounted on the support plate and connected to the belt drive. The inner side of the housing is rotatably connected to a drive gear that is connected to the rotating shaft. The housing is also rotatably connected to multiple meshing driven gears, two of which are also meshing with the drive gear. Multiple drill bits are fixed to their respective drive gears and driven gears.

[0013] Furthermore, a frame plate is fixed on the operating table to surround the clamping assembly, and a slag discharge port is also provided on the operating table. Side guards are fixed at both ends of the top of the two sets of boxes.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] The drilling device for this metal sheet automatically clamps the metal sheet by driving the push plate and the clamping plate with the push cylinder in the clamping assembly. This eliminates the need for manual disassembly and re-fixing, reducing the labor intensity of operators, avoiding manual positioning errors, and improving drilling efficiency and processing accuracy. The movable adjustment assembly enables precise adjustment of the position of the multi-axis drilling device to adapt to the processing needs of different hole positions, improving the versatility of the device. The multi-axis drilling device can process multiple holes in the metal sheet simultaneously, significantly increasing the drilling speed and meeting the needs of mass production.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 The drilling device for a metal plate in this embodiment includes an operating table 1, a clamping component 4 installed at the center of the operating table 1, and movable adjustment components 5 installed on the left and right sides of the clamping component 4. A multi-axis drilling device 6 is installed at the movable end of the movable adjustment component 5.

[0023] Among the above components, the clamping component can automatically clamp and fix the plate, and then the moving adjustment component drives the multi-axis drilling device to adjust to a suitable position to complete the drilling or slotting operation on the plate. Therefore, efficiency can be improved through automation, and efficiency can also be improved by drilling multiple holes in sequence.

[0024] Among them, such as Figure 4 The clamping assembly 4 includes a fixed plate 41 and a mounting frame 43 fixed on the operating table 1. A clamping plate 48 is fixed on the fixed plate 41. Two sets of guide rods 42 are passed through the clamping plate 48. A push plate 45 is fixed between the guide rods 42. A push cylinder 44 is mounted on the mounting frame 43. The piston rod of the push cylinder 44 is fixed to the push plate 45. The top of the clamping plate 48 and the push plate 45 have multiple sets of protruding ends, and an inner platform is formed on the opposite side of each protruding end. The inner platform on the clamping plate 48 is used to support the plate. At the same time, a rubber block 47 located above the inner platform is fixed on the opposite side. A limit block 46 is fixed on the top edge of the clamping plate 48. The limit block 46 is opposite to the inner platform of the clamping plate 48, and its edge has a stop edge that is opposite to the gap between the clamping plate 48 and the push plate 45.

[0025] The clamping plate and the protruding top of the push plate hold the plate in contact, while the inner platform of the protruding end of the clamping plate provides a horizontal support surface for the plate, keeping it stable and preventing wobbling caused by suspension. The rubber block utilizes the elasticity and high friction properties of rubber to prevent the plate from sliding due to vibration during drilling. When the push cylinder pushes the push plate, the rubber block fits tightly against the plate surface, forming a non-slip clamping surface, which is especially suitable for smooth metal plates. The rubber material has a cushioning effect, preventing damage to the plate surface during clamping. To prevent indentations or scratches, and to avoid affecting the appearance quality of the sheet metal and subsequent assembly accuracy, rubber blocks significantly reduce the risk of workpiece damage compared to traditional metal clamps. The limiting block is fixed to the top side of the clamping plate. When the sheet metal is placed in the clamping area, the stop edge of the limiting block can prevent the sheet metal from moving to the side, ensuring that the sheet metal is always in the center position of the clamping assembly, avoiding drilling position deviation due to offset. When clamping the sheet metal, the operator can align the edge of the sheet metal with the stop edge, reducing manual positioning time and improving clamping efficiency, which is especially suitable for mass production scenarios.

[0026] In addition, such as Figure 2 The movable adjustment component 5 includes a platform 51 with four sets of waist holes 52. The strip 51 is fixed to the operating table 1 by screws passing through the waist holes. Two sets of fixing blocks 53 are also installed on the operating table 1. A screw 54 passes between the fixing block 53 and the platform 51. The outside of the screw 54 is fixed in a designated position by multiple sets of nuts. A push cylinder 55 and a push plate 56 are slidably connected and fixed to the piston rod of the push cylinder 55 are installed on the platform 51. The multi-axis drilling device 6 is installed on the push plate 56.

[0027] The four sets of elongated holes on the platform are screwed through to secure it to the workbench. These holes provide space for movement; loosening the screws allows the platform to move along the direction of the holes, enabling coarse adjustment of the multi-axis drilling device's lateral position. A screw rod passes between the fixing block on the workbench and the platform. Multiple nuts on the outside of the screw rod provide restraint, improving the platform's stability. When adjusting by loosening the screws, the nuts are also loosened, allowing the platform to move slightly using the screw rods. After adjusting to the target position, the nuts and screws are tightened. The top-push cylinder is fixed on the table, and its piston rod is fixed to the top-push plate. After the cylinder is activated, the extension and retraction of the piston rod can drive the top-push plate to reciprocate on the table, thereby driving the multi-axis drilling device to move closer to or away from the workpiece, realizing the drilling feed and retraction actions. The top-push plate and the table are slidably connected by a slide rail to ensure that the top-push plate maintains a straight movement during the movement and avoids shaking. This design can ensure that the feed direction of the drill bit is perpendicular to the surface of the workpiece, prevent the drilling from being skewed due to tilting, and improve the drilling verticality accuracy.

[0028] like Figure 3As shown, the multi-axis drilling device 6 includes a support plate 61 fixed on the push plate 56. A rectangular block is formed on the support plate 61. A housing 64 is fixed on the right side of the rectangular block. A rotating shaft 63 extending into the housing 64 is rotatably connected in the rectangular block. A belt-driven transmission device 62 that drives the rotating shaft 63 to rotate is installed on the support plate 61. A drive gear 65 connected to the rotating shaft 63 is rotatably connected at the center of the housing 64. Driven gears 66 distributed on both sides of the drive gear 65 are rotatably connected to the inner side of the housing 64. The driven gears 66 on both sides mesh with each other. The two driven gears 66 distributed on both sides of the drive gear 65 mesh with the drive gear 65. Drill bits 69 are installed on the shaft ends of the drive gear 65 and four sets of driven gears 66. The drill bits 69 distributed on both sides of the clamping space 4 can be changed in size as needed.

[0029] A belt-driven transmission device drives the rotating shaft to rotate, which in turn drives the drive gear to rotate. The drive gear meshes with the driven gears on both sides, thereby driving multiple drill bits to rotate synchronously. This transmission method can achieve single power source driving multiple drill bits. Compared with traditional single-axis drilling machines that drill holes one by one, the processing efficiency is increased several times. Multiple holes on a plate can be processed simultaneously. The drill bits distributed on both sides of the clamping assembly can be independently disassembled and replaced. The corresponding size drill bit can be replaced according to the hole diameter requirements. The housing is fixed on the rectangular block of the support plate and houses the drive gear, driven gears and other transmission components. It can prevent cutting chips and lubricating oil splashes from affecting gear meshing, and at the same time provide rigid support for the gears.

[0030] Meanwhile, a frame plate 2 surrounding the clamping assembly 4 is fixed on the operating table 1, and a slag discharge port 3 is opened in the center. L-shaped side guards 68 are fixed at the opposite ends of the two housings 64 near their edges. The frame plate, fixed to the operating table and surrounding the clamping assembly, forms a semi-enclosed protective area. Metal debris generated during drilling is blocked by the frame plate, preventing it from splashing to the operator or outside the equipment, reducing safety hazards. The slag discharge port in the center of the operating table allows some of the debris generated during drilling to be discharged directly, while some needs to be swept out from the slag discharge port when cleaning the table later. The L-shaped side guards fixed at the opposite ends of the two housings prevent cutting fluid and debris from splashing.

[0031] The working principle of the above embodiments is as follows:

[0032] The plate is placed on the inner platform of the clamping plate and contacts the protruding end. The retaining edge of the limiting block restricts the lateral displacement of the plate, achieving precise positioning. The piston rod of the push cylinder extends, pushing the push plate to move along the guide rod. The rubber block presses the surface of the plate, using friction and elastic buffering to ensure stable clamping and avoid vibration displacement or surface damage. The belt-driven transmission device drives the rotating shaft to rotate, and the rotating shaft drives the drive gear in the housing. The drive gear meshes with the driven gears on both sides to achieve synchronous rotation of the drill bit. The piston rod of the push cylinder extends and retracts, driving the push plate to move linearly, driving the multi-axis drilling device to approach or retract from the plate. Multiple drill bits are simultaneously aligned with the holes in the plate, and multiple holes are drilled in one feed, improving efficiency.

[0033] The entire workflow is now complete, and anything not described in detail in this specification is existing technology known to those skilled in the art.
